Reelights
Postby europa » Thu Mar 22, 2007 1:44 pm
Reelight
I like:
- they require no batteries
- no friction like the old dynamos
- they're always on the bike so I can't forget to pack the rotten things
- the blonde ... err, no that wasn't it ... umm ...
I don't like:
- the 'safety is cool' tone of the website
- they don't mention brightness at all so I'm betting they are 'to be seen' only and don't help you see
- the low positioning which might make then too low to be useful as safety aids
You can buy them off flebay for $42 delivered at the moment.
I'm planning to go riding while my son's at soccer training. That's worked nicely up to now but with dusk encroaching into that time and daylight saving ending soon (boooo!), I need to think lighting. I've got battery lights front and rear the front is just a 5 led light and I'll be riding on unlit bike tracks. I'd also like to do Audax at some point. My thinking is that these reelights would be a useful companion to a 'melt the concrete' headlight.
Any thoughts?

The concept is great, a zero loss dynamo. Still not sure 'bout the mounting, how would they stand up to vibration?

It does mention brightness, ". . . very strong light."
Check out the photo of the dorkmeister on the technology page.
They could have spent a few dollars on an interpreter spell checking their site.
I'd be interested to know how big the magnets are.
I think I'll stick to my regular lights with rechargeable AAAs and a few spare fully charged AAAs as a backup.

Maybe as another set of lights on the bike, but certainly not as the only set.

I am assuming that this would be some form of 'magnetic induction' like the little magnet on the bike computer but the magnet would have to be strong enough to induce a current.
To quote a famous TV bloke,
In this house we obey the laws of Thermodynamics!
If you are generating electricity at the wheel you must feel it at the pedal.
I think that I'll stick with rechargables.

These are questions that have been raised in this thread and I'm sure I'm not the only one who'd like the answers.
I'm in Adelaide and you're in Brisbane so ringing him myself may not be a good idea (I tend to chat).
Thanks for that.

Electromagnetic induction requires work be performed ie dynamo drag, These lights have effectively no moving parts, so going on the very low voltages drawn by LEDS, I don't think they wolud drag any more than your 'puters sensor. The frictional losses in a bottle or hub dynamo is what hurts your legs.tinstaafl wrote: If you are generating electricity at the wheel you must feel it at the pedal.

Agreed, you wouldn't notice the induction in the pedals. Magnetic forces are small and not much power is needed for LEDs. They're low voltage devices.Mulger bill wrote:Electromagnetic induction requires work be performed ie dynamo drag, These lights have effectively no moving parts, so going on the very low voltages drawn by LEDS, I don't think they wolud drag any more than your 'puters sensor.

The added weight on the bike and the fact they don't look aerodynamic would cause more drag.

I'd put that into the same box as any set of lights - the difference being that these are on the bike all the time. Wonder if they have some sort of quick release system. Wonder how heavy the magnets are.tuco wrote:The added weight on the bike and the fact they don't look aerodynamic would cause more drag.

The lights that I am selling do not operate while the bike is not moving. There is an newer version with a capacitor inside available however it has not arrived in Australia yet. (Once it does I will be selling them too.) The lights flash as often as the magnets go past meaning that if you are doing more than about 30 k's an hour the flash turns into more of a pulse. The flash is very bright, even at low speeds. It would be comparable to many of the battery flashers available on the market.
The whole kit weighs about 320 grams including magnets and lights front and rear.
If there are any other questions that you have, I would be more than happy to answer them for you.
Mount Gower has also pointed out that if you want to use them on a bike with flat spokes, you can get so called 'flat spoke magnets' on ebay for a bit of a premium. I have asked the manufacturer if they have any plans to release a flat spoke version but I have not heard anything back yet.
Thanks,
Brendan

Now, back to these lights. Can they be mounted elsewhere? For instance, my bike had mounting points on the fork for a front carrier - could they be mounted there. How about on the rear rack supports. Just trying to get them closer to a driver's line of vision (yes, I know, it shouldn't be needed but ...)
Any thoughts on how much dearer the newer version will be? And when they'll be available?
Richard
and thanks to Mountgower for organising this

Unfortunately the lights are designed as a fully integrated package so they will only mount at the wheel hub. A dedicated tinkerer could probably re-wire them to fit where they wanted, but that would be very difficult. I think you'll find that the lights are quite visible where they are. I have them pointed slightly upwards so they are shining into a drivers face when he is about 10 meters behind me
No idea on pricing of the new version, but I can't see it being too much dearer. Maybe an extra $5 or $8... Also, I don't know if they will be a constant on or a flashing light. I'll have to wait until I can get some in my hot little hands
Yeah MG has been great. he started recently at my work and we're the only 2 cyclists in an office of 30. It's great not to be all by myself any more!
Cheers,
Brendan

I've had a look around the site and found this,
It's an extender bracket for disc brake applications, looks to me like a competent fiddler could work something similar up, just as long as the magnet mountings can be made to line up.
Thinkin' aloud

I'm still trying to invent something to stop the wind blowing my candles out when I'm riding. I just about give up and will have to get some lights.Mulger bill wrote:This looks like a job for BicycleWA
I wonder how these will mount to the wheel with the front rack hardware and extra lugs on the tourer fork?
Kev.

Making the magnets fit out near the rim would be the only question IMHO.
Cobbling up brackets for rackmount holes using the factory units as a template should be a doddle.

Most bikes should be OK, it's just us tourers are a difficult bunch.
You could mount them higher up with one of those brackets that come off of the brake mounting points. There is a bracket designed for racks that allows racks to mount to the brake pivot points. Using one of these, the light could probably mount OK, but you wouldn't have the magnet going past it as much unless you were riding faster
